Application filed December 17, 1915. Serial so. crass.

-Arbor, in the county of "Washtena-w and State of Michigan, have invented certain new and useful Improvements in indicators;

and I do hereby declare the following to be a full, clear, and exact dGSCIiPiJlOIl of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This inventwn relates to new and useful improvements in indicators and the principal object of the invention is to provide a device which will indicate to the driver of a motor vehicle the direction in which a passenger is desirous of traveling.

Another object of the invention is to provide a means for directing the driver in event that he is not familiar with the location of various buildings and the like.

A'still further object of the invention is to provide a means for indicating where and when to stop.

A further and more specific object of the invention is to provide a device actuating by electro-magnets which are energized upon the pressure of the passcngers thumb on certain buttons or combination of buttons.

With these and other objects in View, the

invention consists in the novel combination the switch.

and arrangement of parts which will be fully set forth in the followingspecificationand accompanying; drawings, in which:

Figure -1 is a viewillustrating this iniproved device attached to a motor vehicle of the usual construction;

Fig. 2 is a vertical sectional view of the attachment.

Fig. 3 is a side view partly in section of Fig. 4: is a top plan view showing the ind icating hand.

Fig. 5 is a plan view showing the dial and hand removed and illustrating the interior construction of the casing. p i

Fig. 6 illustrates the wiring diagram.

Referring now to the drawings by characters of reference, the numeral ldesig'nates as an entirety the supporting structure for the indicator casingcomprismg the base blocl; 2 having formed at its'outer end the/inclined face 3. This face 3 forms the rest on which the indicator is secured. l

The indicator casing is designated glen- -bers which we erally by the numeral 6 and comprises a cylindrical casing 7, the lower end of which is closed as at 8 and secured to the base block 2 as at 9. Formed in the outer end of the casing-i are the threadsv 10,.which cooperate with the threaded ring 11 in supporting the glass crystal or cover l2 which rests on the annular shoulder 13- formed on the interior of the casing.

Secured centrally of the bottom wall 8 of th'e casing is a suitable sleeve or bearing 15 in which the shaft 16 is journaled. The upper end of the shaft extends through an opening 17 formed in the dial 18 which is supported on suitable lugs 19 ,formed at spaced intervals along the interior of the casing 7.

Secured on the upper end of the shaft is a suitable hand 20 and secured near the lower end of the shaftis a sleeve 21, formed with the armature 22, which is attracted by the cores of the magnet 23' as illustrated in Fig. 5. These magnets 23 are positioned at spaced intervals around the interior of the casing 7 so that their cores are disposed in such a position as to attract the armature. 22. Secured to the shaft 16, in angular relationto the armature and hand, is a non-magnetic weight 24 which, when none of-the magnets are energized, holds the hand in a neutral or non-indicatingposition. I 1

A. suitable sight opening 25 is formed in the dial intermediate two of the magnets 23 and a lamp bulb 26 is so diately beneath the sight 0 ening. 25 in a suitable space.

In ordertocontrol the energization of -the electromaguets' 23, there'is provided a.

ported, immecasing 28 provided with and closures 29.

@ne of the end closures is formecl with an opening 30, through which the Wires enter the casing and a suitableinsulating block 31 is supported on the fiodr of the casing and forms a su port for th'e contact mam be more fully hereinafter described. Formed at spaced intervals at ing material 81 are the openings 32 throu h which the push buttons extend. he

va point diametrically opposite the insulatinner ends of these push buttons hear against the contact springs 34 which are secured in any suitable manner to the insulating material. suitable contact point is disposed beneath the contact spring so that when its respective push button is pressed the spring 34: will be forced into engagement with the point 3'5'50 that the circuit will be completed through its respective magnet. \Vhen not in use the device is hung upon the back of tle front seat of the car by the hook, as shown in Fig. 1.

Upon referring to the wiring diagram illustrated in Fig. (3, it will be seen that the current passes from the battery 36 into the Wire 37 and thence through the branch wires 38 into one of the contact springs 34, thence through the contacts 35 into the wire 39 and to the lamp 26 hereinbefore referred to. The current then passes through a branch wire 40 into the common return Wire 41 and back to the battery.

It will thus be seen that when the button designated by the character operated, the filament of the lamp 26 will glow and thereby illuminate the sight opening 25 to indicate to the driver to stop. Upon manipulation of the press button designated by the character A, it will be seen that the current will flow through the wire 37 into the branch wire 41 through the conush tact of the push button A into the wire 42,-

i thence to the magnet designated a and through the branch wire 43 connected thereto into the common return wire 41 .here'inbefore referred to. 'pressure on the push button B will ener- Likewise the gize the magnet I), while pressure on the push button C will energize the magnet c. The energization of these magnets will cause the armature 22 to be drawn toward the cores and the hand will move over the face of the dial to indicate the direction to be taken. When none of the magnets are energized it will be seen that the weight An indicator comprising a casing electromagnets mounted within said casing and arranged in annular series. a lamp bulb within the casing in place of one magnet, a sleeve secured to the. bottom wall of said casing, a. shaft rotatable in said sleeve, a dial secured within the casing in spaced relation to the bottom wall, said dial having a central aperture arranged therein for 1 the reception of the shaft, said dial also having alateral aperture formed therein to provide a sight opening through which the lamp bulb is visible, a hand secured to the outer end of the shaft and operable over the face of the dial, an armature mounted on the shaft and adapted to be attracted by the electro-magnets, said magnets being adapted to be individually excited, the armature and hand extending in the same plane from the axis of the shaft, :1 weight, mounted on the shaft and adapted to hold the hand in a non-indicating position when the magnets are denergized and a transparent cover for the casing adapted to completely house the hand and dial.

In testimony whereof I afiix my signature in presence of two witnesses.
